I just installed CM 11 on my xperia V but then I'm experiencing this terrible super fast battery drain. It's been 3 days. The first night I installed it it drained my whole battery while I was asleep. Usually standby time is great before I installed CM 11. Maybe its because of the sony stamina extended standby mode thingy. Last night, I reckon that it's probably because of the background process and the wifi, so I reboot the phone (so that all apps are killed) and didn't turn on the wifi. It eats 7% of my battery. Dafuq???
So, I checked the battery stats and 82% of my battery is used on android system. Then, I turned off location access. Brightness is at its lowest. It was on aeroplane mode. Bluetooth is off. I underclock the device to clock only at 1 ghz and i clear all recent apps. Only the wifi is turned on. I only left it for half an hour without even touching it but my battery went down from 100% to 93%.!!! Can you imagine?? This sucks. Can anyone please help me with this issue? Imagine after an hour my battery would be at 80%. That means i can only use the phone for 5 hours!! That is without any connectivity at all with slow processor and low brightness. If I were to push it to the max it would take maybe 2 hours of usage. I uploaded the battery stats included with this thread.
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Xiaomi Mi 9's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
standby about:
1-1,5 % per hour without ambient display
2,5-3% per hour with ambient display
standby drain is quite bad, LG V30 has half consumption in standby
MIUI 10
High battery drain in backgound too.
I usually lose 10% in 8 hours during night.
Standby drain is high; significantly higher than my other phones. On average, my phone drains about 1.8% per hour with AOD turned off. My Pixel 3 XL drains 0.5 to 0.8% per hour with similar settings and the same SIM card.
If you are running Global rom it could because it's trying to connect to multiple networks. Maybe both European and chineese network.
Download EX Manager and put it on Powersaver Mode. 9h and I just lose 10% of battery while watching BBT 5 episode and played 1 album to get me asleep. Lol
Hi there. 8 hours of sleeping time drained 1%.
I'm using Xiaomi.eu version.
With Global EEA it drained about 4% in 8 hours also
It drains about 1% while asleep 8hrs on airplane mode.
for me it drained up to 2% per hour.
I could reduce it to 0.5% per hour just by turning off bluetooth, maybe that helps you as well
In Global dev ROM my mi 9 was not entering sleep mode at all, it was consumed at least 2% per hour.
I'm now on Xiaomi.eu and it sleeping great.

Global Dev (stock kernel) gives me less than 0.5 % / h battery drain at night. Network and WiFi always running, no airplane mode. Just Bluetooth usually is switched off since I only need it in the car. No snake-oil apps for 'better battery live' or similar battery voodoo.

For me mit official stable it is a little more than 1% per hour during night, mobile-stand-by as well as android system are draining the most battery.
Waiting for Unlock in 5 days.
Xiaomi.eu doesn't really improve battery life for me. Androidsystem drains about 20% and I have no idea why. I lose about 10 percent at night (sleeping around 6h), so that's pretty much considering the other reports... also I only get like 3-3,5h SOT, because of the drainage. Can't figure out why, though.
Hey there have Battery Drain too. i have the Transparent Edition with Global Rom for me to use in EU with German Language. It is unlocked and has the Mi Recovery. Can i only flash with Mi Tool the Xiaomi.eu rom or will i have to flash custom Recovery?!
I'm on latest ROS, last night ~8 hours standby + airplane mode = 1%
Global stable official, i get 1% drain on 6-7 Hours, signal on so i can be called, wi fi off
MIUI 10.2.9.0, everything is on (wi-fi etc.). Mifit is permanently connected to my BIP, kate mobile is connected to VK. 4% for 8 hours this night.
yeah. the standby drain is not good at all
lost 3% in 5 hours ,with powersaving mode on(scheduled in settings to turn on between 23:00-07:00)
wifi off, bt off, mobile data off...
only WCDMA/LTE enabled
latest global rom
Its because the phone is set to scan for chinese network by default (TD-SCDMA), even though Its a global version.

Really? How to fix that?
Any ideas?
That's NOT true. Switching to LTE/WCDMA give the same battery drain.
That's only the preferred network.
I have a Huawei Mate 10 pro and have been using it for about 9 months.
I used to have amazing battery life with close to 8-9 hours of SOT ( and still had like 20% remaining never really went too low).
Recently I have been getting a battery drain of over 20% per night even if the phone is in doze mode.
I tried every method of finding out the battery drain and could not find it, assuming its a system bug i reset the phone but it did not fix anything.
I have wifi scanning and data always on turned off , so it disconnects mobile data and wifi if the phone is not being used.
I have just factory reset my phone and am posting screenshots of all my battery monitoring.

Please help me identify what is causing this battery drain.
Hi all,
My phone drained 14 percent battery yesterday while idle for 9 hours. The interesting thing is when i add the mAh usages that i see in battery and performance tab it only adds up to 6 percent battery usage. ( i calculated and confirmed with time that 40 mah is aproximately 1% battery)
Also this morning i am seeing an unusual drain as well while the screen is on, it drained 5% but it should have draned only 3% because it says it drained 138 mAh.
Does anyone have any idea about this problem?
This also happened 2 weeks ago and the only thing common both days were, i charged my phone slower (charged using usb on the car) instead of using fast charging.
I also leave the screen shots that shows the battery usage.
Put the phone into Airplane mode when idle: this may save some battery.

yes of course but the battery drain I explained sometimes happens I actually think its a battery indicator bug. Because it shouldn't be draining this much battery because it doesn't show any unusual drain on battery information screen contradicting the percentage lost (14% battery was drained but according to battery information screen it should be 6%)
How is everyones standby Drain?
Mines appaling. Even over night it drains about %6 with nothing running and airplane mode on! I've already reset it since the April update and cleared cache etc. SOT is good enough but obviously I will manage less of that with the poor standby drain.
That's about the same for me. 7 or 8% but no airplane mode
I have bixby routine that enables power save mode and disables wifi and mobile data from 22h00 until 06h30 the next day...I loose perhaps 2-3% for that period. Without power save I loose for the same period of time 6-9%
~3% overnight drain. No flight mode.
I lose around 4-5% in 8hrs. That is with WIFI on and Flight mode OFF.
mine has gone down hill over the past few days - not sure - but went from 5% overnight to 15% - didnt change anything - just installed the app updates that were available so am thinking something with an app - but nothing showing up in the battery life check
2-3% overnight drain with everything on, get the galaxy max hz app and enable doze and powersaver mode when screen is off, before mine was 6-8% a night now its 2-3%
1% per hour on average when left idle overnight with wifi on

Is this only in the payed version, because my issue at the moment with this app is, when my phone goes into battery saving mode, when it comes back out (with bixby routine) the phone is stuck in 60 hz. Basically, i have to manually set up the adaptive refresh rate everytime.
Is this problem gone with the payed version? Or am i doing something wrong.
Cheers
